SOLVED: Create a VHDL code for a 4-Bit Adder/Subtractor using a full adder.4-bit full-adder circuit:Below is the schematic of the 4-bit full-adder subtractor you will implement in Lab 6. It has two inputs, A and B, which are both 4-bit numbers. The sum of these two numbers will also be 4-bit, plus a carry-out bit if overflow occurs.Selector bz@oUnsigned OverflowFAFAFAFASigned Overflow

i. Draw a 4-bit parallel Adder/subtractor using 1-bit full adder blocks and inverters. Implement the Verilog code for a 4-bit parallel adder using a full adder (ii) and verify its truth table using a test bench program. ii. How can a full adder be converted into a full subtractor? Construct a full subtractor. Write down the truth table and Boolean equations for the outputs difference (i) and borrow-out (Borout) of the subtractor by using edaplayground.com. Sele
